Hello I wrote about this subject some month ago, but just now I found out that the problem occurs also with more recent versions of comint.el. The problem I describe occur for xemacs.21.4.21-mule -vanilla xemacs.21.5.29b -vanilla The issue is the following. Matlab is commercial product provided by Mathworks. If I am not mistaken it is released every 6 month. There is a lisp package, matlab.el, now maintained by Eric Ludlam, which helps editing matlab files but also allow to connect to the matlab engine via matlab-shell and it also allows to debug (In a way similar to the emacs shell command). The current version of matlab is 3.3.1. Now comes the issue: When I use an older version of matlab (release 2004) I have no problem to use the matlab-shell command. When I use a more recent version (release 2008, newer version I don't have), then there is the following problem. When I use comint.el from xemacs-base 2.10, everything is fine. But if I use either an older or a newer comint version, say from xemacs-base 2.19, then the matlab-shell command tries to start matlab but then I obtain an error M-Shell aborted There is no bugtrace and I have no idea how to debug it. There are a lot of changes between these two comint.el version so I don't know how to track down this error. Can anybody who knows about the recent changes in comint.el help me, because I would like that more recent versions of xemacs-base would allow xemacs users to use matlab, right now they have to downgrade the comint.el version which is not a good solution. regards Uwe Brauer _______________________________________________ XEmacs-Beta mailing list XEmacs-Beta(a)xemacs.org http://lists.xemacs.org/mailman/listinfo/xemacs-beta
